Abstract: <P>PROBLEM TO BE SOLVED: To enhance response and reduce power consumption of a motor in a brake device for applying a brake force by pressing a friction member by transmitting rotational force of the motor.  <P>SOLUTION: A speed change gear system comprises non-circular gears 10 and 9 installed on a shaft of the motor 11 rotatively driven by pressing a brake pedal, and is shifted from a high gear ratio to a low gear ratio along with rotation of the motor.
